ADDITIONAL CROPS - RICE POST-EMERGENCE SEEDLING TREATMENT - HYBRID RICE SEED PRODUCTION
Do not apply this product through any type of irrigation system.
NOTE: Gibberellic Acid is an extremely potent plant growth regulator. For best results, read all directions for use thoroughly. Consult your local experiment station specialist, distributor, or the Nufarm agricultural specialist in your area for the spray schedule best suited to your conditions.
Discard any unused spray material at the end of each day. Prepare solution concentrations by mixing the required amount of product with water only in a clean, empty spray tank. Refer to individual crop sections and rate conversion tables provided in the labeling for the amount of GibGro to be applied.
Use only as directed. The label should be read thoroughly and understood before making applications.
Effectiveness requires that all parts of plant or crop must receive spray or desired result will not occur, so spray thoroughly. When a range of rates is indicated, use the concentration and spray volume recommended locally.
Data concerning the compatibility of GibGro with other agricultural compounds is not available, except where specified.
Refer to the label regarding tank mix information.
SPRAY INSTRUCTIONS FOR ADDITIONAL CROPS
RICE POST-EMERGENCE SEEDLING TREATMENT
(All states except California) For use as a post-emergence seedling application on rice grown in the United States to promote more uniform and vigorous growth prior to permanent flooding. Early season foliar applications of GibGro will promote vigorous and more uniform seedling growth of rice prior to permanent flood establishment. This will allow earlier (five to ten days) flooding of drill or dry broadcast seeded varieties and is particularly effective on semi-dwarf varieties. Early flooding may reduce additional flushing costs associated with a delay in permanent flooding, weed infestations and the number of herbicide applications as well as promote earlier and more uniform grain maturity. Gib-Gro application may result in a temporary lighter green foliage color due to accelerated growth rates.
Do not apply when rice is subject to drought stress conditions. GibGro can be tank mixed with most commonly used rice herbicides and fungicides. When GibGro is applied in tank mixes with Arrosolo, Riverside Propanil 60DF, Stam M4 combined with labeled herbicides, Stam 80EDF or Wham EZ, plus a recommended adjuvant, the use of a surfactant is not necessary. Do not apply with Whip IEC or Whip 360.
GibGro applied between split-boot and 100% heading can increase panicle height of semi-dwarf rice.
This may facilitate harvest efficiency in the field by allowing the rice grain to be cut above the leaf canopy at faster combine speeds and at reduced vegetative load. Grain quality and maturity can be advanced with the promotion of tiller panicle development. Heading applications to the first crop can also accelerate regrowth of second crop rice. This can result in earlier second crop maturity and maximize grain yield.
HYBRID RICE SEED PRODUCTION (All states except California)
Make 1 to 5 applications at regular intervals during the heading period to promote main culm and tiller panical extension.
Application Equipment for Post-Emergence Seedling Treatments and Hybrid Rice Seed Production
Apply GibGro by fixed wing aircraft with spray systems capable of producing a uniform medium to fine spray droplet pattern of 10 gallons per acre (GPA). Do not apply less than 3 GPA of total spray volume.
Low pressure ground sprayers equipped with boom and flat fan nozzles: apply 10 to 15 GPA spray volume.
